This study carried out the analysis of the characteristic of vertical odor spread in the condition of having a big vertical opening on the top layer of a food court, and also made an analysis of pressurization(vertical pressure differential) and horizontal pressurization on the top layer for control of odor spread, and also made an analysis consequential on a line diffuser design condition for blocking odor spread onto the top layer; the major results from these analyses are as follows: First, the results found that the odor concentration, which spread toward the top layer through a vertical opening from the lower layer, decreased in reverse proportion as pressurization amounts on the top layer increased up to 5¢¦50% based on inhalation displacement(32.16kg/s)on the top layer, and the spread channel of odor was consistent with air flow. The design of a horizontal pressure differential on each layer was analyzed to be a major factor directly and indirectly influencing the formation of the pressure differential between the front and rear of an opening, and the control efficiency of the line diffuser. |
